API overview

The Pickware GraphQL API gives merchants using Pickware ERP on Shopify access to their ERP data and selected write workflows: stock, warehouses, purchasing, goods receipts, orders, documents, products, and related metadata. The API is date-versioned, and the version is part of the endpoint path: this reference documents the schema served at POST /api/graphql/2026-06-unstable. The 2026-06-unstable schema is an early preview and may still receive breaking changes before the first stable schema is released.

Start with the getting started guide, then use this reference to inspect the available fields and input types. The schema is also available as an SDL file, for example to generate client types.

Useful entry points:

• Products query for product and variant lookup.
• Stock query and WarehouseStock query for stock reads.
• setStockAtBinLocation, adjustStockAtWarehouse, and transferStock for stock movements.
• Supplier orders and createSupplierOrder for purchasing workflows.
• Product-supplier configurations for purchasing metadata.
• Warehouses and bin locations for warehouse structure.
• requiresScopes directive for read and write capability metadata.
